Try looking in the book, "Palm OS Programmer's API Reference," in the section, "System Management," subsection "Virtual File System Manager".
That said, Google the internet for a GPL library called UniForm.prc, written by Mert Saglam. He also has source for an application, TexT (hard to Google that), demonstrating how to use his library. It will save you a lot of work. -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
